An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC), aka 'Netlogon Elevation of Privilege Vulnerability'.

Criminal small talk in underground forums offer critical clues about which known Common Vulnerabilities and Exposures (CVEs) threat actors are most focused on. This, in turn, offers defenders clues on what to watch out for.
An analysis of such chatter, by Cognyte, examined 15 cybercrime forums between Jan. 2020 and March 2021. In its report, researchers highlight what CVEs are the most frequently mentioned and try to determine where attackers might strike next.

Threat attackers continue to exploit the Microsoft Zerologon vulnerability, a situation that’s been a persistent worry to both the company and the U.S. government over the last few months. Both on Thursday renewed their pleas to businesses and end users to update Windows systems with a patch Microsoft released in August to mitigate attacks.
Despite patching awareness efforts, Microsoft said it is still receiving “a small number of reports from customers and others” about active exp...
Microsoft today warned that threat actors are continuing to actively exploit systems unpatched against the ZeroLogon privilege escalation vulnerability in the Netlogon Remote Protocol (MS-NRPC).
"Microsoft has received a small number of reports from customers and others about continued activity exploiting a vulnerability affecting the Netlogon protocol (CVE-2020-1472) which was previously addressed in security updates starting on August 11, 2020," MSRC VP of Engineering Aanchal Gupta sa...
